In case you've been looking for Thomas Henry books since the demise of Midwest Analog, this was posted to the Synth DIY List:

Hello there, boys and girls!

I've got a (IMHO) fairly exciting announcement to make: John Mahoney
and I are putting together a joint venture to, amongst other things,
reissue the Thomas Henry "Cookbooks"!

We've got the blessings of Mr. Henry himself, and starting sometime in
March (yes, of THIS year) Magic Smoke Electronics (tm) will be
publishing the "Electronic Drum Cookbook." This will be followed by
the Noise, 566 and 3080 books (approximately in that order). There
will be other books and goodies, but too many details remain to be
ironed out to discuss everything just yet.

We'll have an online site to take orders, but PLEASE no orders yet.
Like I say, we should be ready to rock in some time in March.

John and I would also like to thank Scott Stites for his help and
recommendations (and for making the introductions), and of course,
Thomas Henry for allowing us to share this great source of DIY info.
We're pretty excited about this, and we look forward to making these
books available again.

yeah I found that- but I ignored it. Magic Smoke must be an American expression? I've never heard of that here. "Up in Smoke" maybe??

The Thomas Henry story is a bit of a strange one. Retiring from the electronics business- yes I can relate to that, but dropping all your publications and books too?- AND making sure that no-one can link anything from anywhere- well that's just plain strange. Someone must have really pissed this poor chap off.

Hi V-un-V,

Sorry, been scarce for a while (work related - I'm currently in Illinois doing some work...hmmm, broadband at the hotel - sha-weet!).

Thomas wasn't pissed off, chuffed, or angry - there were myriad reasons for him folding up MAP. I actually was on the phone with him a bit around that time, and we had a long discussion or two about it. Let's just say, it wasn't anything that made me want to start a business anytime soon.

Tom's always been very protective of his work - before and after MAP. As for Magic Smoke, I hope they step up to the plate soon. Tom had some really nice circuits a couple of summers ago - he was considering at least two new synth related books that I was aware of at the time. In fact, I've got a copy of the manuscript for one of them (makes me wanna cry when I look at it - it so *needs* published). He'd send designs, I'd breadboard them - some really cool stuff. Tom is an ace at wringing the very last bit of magic out of an IC, that's for sure. I'm pretty certain Magic Smoke has the rights to at least one of those designs, a really sweet one (but I canna speaka no more about it).

March is the target date and......hmmm, wait a minute........bit late for that.

The only info I've got is a post earlier this week on Synth DIY from John Mahoney which pretty much amounted to 'soon'. Big help, there, huh?

The hold-up is the transcription of the books - they're being put into PDF format. A lot of the schematics and illustrations had to be re-drawn. Thomas used some older DOS based program which Mark and Tim eschewed for something that would work on their computers.

A bit more info from Magic Smoke on the Synth DIY list. Pay particular attention to the filter Tim Parkhurst speaks of. I was at the right place at the right time and was able to breadboard the filter as Tom developed it. Mark my words: this is one hell of a sweet filter. I'd call the sound somewhere between a Moog Ladder and an SSM2040. Very quiet, creamy resonance, dare I say 'phat' sounding?, no CV 'thump'. One of Tom's best creations by far. If I were a commercial synth builder, this would be the filter I'd license to put in it.

The quadrature stuff is really just icing on the cake. There's a switch to DC or AC couple the filter, and it makes an awesome VC slew generator, with corresponding phase on the quadrature outputs. Resonant Cutoff goes low enough to serve as a great, very slow to audio quadrature LFO.

Guys, reserve an SSM2164 - you will not regret it.

Being able to even talk about it now feels so good........

Hi Matte,

Shameless plug dept: Magic Smoke Electronics has a Thomas Henry
designed VCF/Quadrature Oscillator kit based on the 2164. We're even
reviewed in the June issue of Electronic Musician. We'll soon have
PCBs and parts kits. www.magsmoke.com

yes the 2164 has a bright future in sound synthesis... the henry project sounds good, i like all of what i've seen of his designs so far. i just thought i'd direct ya'll to the work of another chap by the name of osamu hoshuyama, who has done some work with the 2164 as a VCLow Pass and All Pass filter, not to mention loads of other coolness, alot of which while he was still in high school. wow.

the page is called Unusual Synth Circuits and hosts some work by Mike Irwin, too, including a cool implementation of a CMOS VCR. so check it out if you haven't.

Thought I'd lay this on the electro-music group (originally posted on the Synth DIY list today):

Hi Guys and Gals,

Just a few (like 7) printed hardcopies of Thomas Henry's Electronic
Drum Cookbook left. The SDIY special is $10 plus shipping ($2 US,
contact us for international rates), and you can order 'em by sending
an email to magsmoke@gmail.com

Back to what you were doing.
